Serial no. 419,170.

This invention relates particularly toa del for actuating the elementwith the proper sequence to provide a date or other stamp on the back ofeach label preferably near the center thereof; to provide thisconstruction 10 so coordinated with the pickers that it constitutes verylittle additional mechanism to the mechanism ordinarilyemployed forpicking purposes, and thus entails comparatively little expense, and toprovide an arrangement for this purpose involving comparatively fewmotions.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which Fig. 1 is aside view of a labeling machine constructed in accordance with thisinvention, provided with a dating device;

Fig. 2 is an end elevation of the machine showing the mechanism foroperating the dating means particularly;

Fig. 3 is a horizontal sectional view on the line 33 of Fig. 1, showingthe inking of the dating stamp;

Fig. 6 is a side view of the inside of a part of the inking device takenin the direction of the arrow 6 in Fig. 1.

The invention is shown in a form in which it involves a labeling machineof a type now 50 well known. This machine comprises a power shaft 10delivering power through gears, .not shown, to a rotary table 13carrying .the bottles 14, or other articles to be labeled, around in acircle.

The ordinary pickers 15 are spaced apart and apply gum or paste toeachlabel in two spots near the opposite ends. These pickers are mounted toswing and slide on a rod, operated by a cam 17 on the shaft 10.' Thiscam as usual operates a lever 18, pivoted on a stud 34., and anadjustable link 19 connected with an arm 20 which, with the holder 21 ofthe pickers 15, constitutes a lever pivoted on the rod 16. Theseelements are shown for the purpose of operating these pickers back andforth. They are also operated along the rod 16 by a cam 22,0n the shaft10, lever 23 and a grooved element 24: secured to the frame 21 on whichthe pickers are mounted. These parts are all old.

It is also old to supply paste or gum to the pickers from a gumming roll25 which is reoiprocably mounted in inclined guides 26 and moves up anddown thepickers. ,The means for operating this roll 25 is notillustrated. It is also old for these pickers to move forward toward thelabel holder after the roll 25 has descended beyond their ends and toengage the labels L between the label holder fingers 28 and take it awayas shown in dotted lines in Fig. 4.

On the shaft 16 is an'arm 30'having an extension 31. This arm is swungon the rod 16 by a cam 32 on the shaft 10, a lever 33 pivoted on thestud 34 and an adjustable link 35. These parts, it will be seen, operatein the same way as the corresponding parts for operating the side or endpickers 15.

A dating stamp 37 is employed on the extension 37 to date or otherwiseidentify the labels on the back. The date is stamped on the labels at apoint between the two areas of gum provided by the pickers 15, in otherwords, on an ungummed area. It is placed on the labels where it isentirely concealed ordinarily so that if anything goes wrong with thelabelsafter the goods are sold, the date or the number of the operatorcan be identified by taking the labels off.

The dating stamp 37 is operated by the is adjustably mounted a frame 44.It can be.

adjusted longitudinally in a slot 45 .and moved pivotally and held thereby screws 46. On the end it is provided with an inking roll 47. Now theoperation of the cam 40 moves this roll from. the position shown in Fig.4, in which it is receiving ink, to the position shown in dotted linesin Fig. 5, in-which it is,

inking the die ortype, pad 37 and back again.

The ink is supplied from a fountain 50, which canbe filled as desired,and has a valve 51 which is adjusted to allow the ink to descend adropat a time onthe outer surface of a Verticalroll 52. This roll isfreely supported in a bearing on a bracket 53 by means of anarm 54 andadjusted in proper position so that the drops will fall on its surface.The

roll '47 is also vertical and as it comes back into thepickerstandfifiin which the. roll 52 is located, it will engagethe surface of the roll52 and rotate both rolls on their own axes-so-that with the continuedmotions they will both. performicomplete rotations eventually and ther0114? will be inked.

The operation is obvious. When the pickers 15 move up to the gummingroll and receive gum on their surface, they dating stamp 37 is held backaway from it so -that it will not receive any gum. At a later stage itis.

advanced slightly and the roll 47 brought into contact with it toiinkit, as shown in dotted lines in Fig. 5. Then the stamp moves for- Wardagainst the label ina dry spot after the gumming roll has descended outof the way. The parts :are retracted as indicated in Figs. 4 and 5 andin a similar way-to that shown on the first two figures.

This provides a simple way of dating or otherwise stamping the backs oflabels without addingany greatamount of mechanism to the machine andthatin suchposition that it is found to coact in proper sequence withthe; rest of the operations and .is not likely .to get out of placeoro-utof order. In this way the-dating mechanism can beadded to theexistingmachine at very little expense and without appreciableadditionalcost for re arrangements and repairs,

I Although-I hafveshown and described only one form' of the inventionand shown both of them asapplied to a particular type of labelingmachine, I am aware of the fact that modifications can be made in theparticular form shown and that it can be applied, with or without;modifications, toothertypes of .labelingi machines withoutadepartingfrom the scope of the invention as expressed in the claims. Therefore, Ido not wish to be limited to all the details of construction hereinshown and described or to the particular form of labeling machine, butwhat I do claim is 1. In a printing device for a labeling machine, thecombination with an oscillatable shaft having an arm thereon, a printingstamp carried by said arm, means for swinging said shaft to bring thestamp into contact With a label, an inking roll, an oscillatable arm onwhich the inking roll is mounted, and means for moving said oscillatablearm to move the inking roll across the printing surface of the stampwhen the stamp is retracted away from the label to prepare the S0 stampfor the next printing operation.

2. In a label printing device, the combination with a printingstamp andmeans for moving the stamp forward it to the rear or inner surface ofthe label in an unpasted portion thereof, an oscillating shaft, aninking roll carried by said oscillating shaft, means for turning theshaft to bring theinking roll into contact with the printing surface ofsaid stamp when it is drawn back away from the labels, and an inksupplying roll in position for the inking roll to be brought intocontact with it when the inking roll is retracted for supplying theink=j1 ing roll with ink.

3. In a label dating device, the combination with a main shaft, two camson the shaft, a dating stamp, means'operated by one of said cams formoving the dating stamp into con 1 tact with a label and back again, aninking device comprising a shaft having an arm thereon, an inking rollon said arm in position to move across the type face of the stamp uponthe oscillation of the shaft, and means operated by the other cam foroscillating the last named shaft.

4. In a label dating device, the combination with a stamp for dating thelabels and means for moving it into and with them, of a main shaft, asecond shaft, means for oscillating said second shaft as the first shaftrotates, an arm adjustably mounted on the second shaft, an inking rollon said arm in position to move across the face of the' type on thestamp during the oscillation of the second shaft, an inking roll inposition to be engaged by the first roll when it is retracted, thesecond roll being freely rotatable on its own axis, and means'for inkingthe second roll.

5. In a label dating device, thecombina tion with a stamp for dating thelabels,- and means for moving it-into and out of contact with thelabels, of a main shaft, a cam on the and back to apply 85 out ofcontact to move across the face of the type on the stamp durin theoscillation of the second shaft, said roll eing mounted to turn on avertical axis on said arm, an inking roll also mounted on the verticalaxis in position to be engaged by the first roll when it is retracted,the second roll being freely rotatable on its own axis and adjustable,and means for causing ink to drop on the cylindrical surface of thesecond r011, whereby as the two rolls come into contact time after timethe ink will be spread out on them.

In testimony whereof I have hereunto affixed my signature.

CHARLES H. OSLUND.
